What pytest-bdd is

pytest-bdd is a free, open-source Python package for automating requirements tests with behavior-driven development. It implements a subset of Gherkin and runs scenarios as pytest tests, without a separate test runner. Feature steps can reuse pytest fixtures through dependency injection, and step definitions can parse arguments with string, parse, cfparse, or regular-expression parsers. Its scenarios helper can bind scenarios from feature files or folders, including recursively discovered files. Scenario outlines support parameterized cases, and the documentation covers multiple tagged example tables. Step functions can receive Gherkin data tables as lists of rows and docstrings as strings. A documented browser-testing example uses pytest-splinter to provide a browser fixture. Installation uses `pip install pytest-bdd`. The package requires Python 3.10 or newer and lists Linux, macOS, and Windows among supported operating systems. PyPI lists version 9.0.0, released September 30, 2026, under the MIT License.
